Q.  My crape myrtles have splits on the bark.  What is going on? A.  Your crape myrtles appear to have sun scald.  Crape myrtles, Lagerstroemia indica, are considered a relatively problem-free tree. The Clemson Cooperative Extension website cites the most common problems as powdery mildew, Cercospora leaf spot, aphids, Japanese beetles, sooty mold, and the recently recognized crape myrtle bark scale.

We tend to associate pre-emergents with spring because that is when we apply them to take care of crabgrass and other summer broadleaf weeds. I know for my lawn, applying pre-emergent herbicide is...

Tales From the Help Desk : Christmas Cactus

Q.  How do I care for a Christmas cactus so that it blooms well for Christmas? A.  Christmas cactus, Schlumbergera x buckleyi, is native to tropical rain forests.  It should be planted in a soil mix that is high in organic material but drains well.  It likes to be root bound, so don’t feel you have to keep putting it in a larger pot each year. Keep the soil moist from spring through summer but let the soil dry out...
